Probing Measurement Induced Effects in Quantum Walks via Recurrence
Thomas Nitsche, Sonja Barkhofen, Regina Kruse +7
Measurements on a quantum particle unavoidably affect its state, since the otherwise unitary evolution of the system is interrupted by a non-unitary projection operation. In order…
A detailed study of Gaussian Boson Sampling
Regina Kruse, Craig S. Hamilton, Linda Sansoni +3
Since the development of Boson sampling, there has been a quest to construct more efficient and experimentally feasible protocols to test the computational complexity of sampling f…
Probing free-space quantum channels with laboratory-based experiments
Martin Bohmann, Regina Kruse, Jan Sperling +2
Atmospheric channels are a promising candidate to establish secure quantum communication on a global scale. However, due to their turbulent nature, it is crucial to understand the…
Heralded orthogonalisation of coherent states and their conversion to discrete-variable superpositions
Regina Kruse, Christine Silberhorn, Tim J. Bartley
The nonorthogonality of coherent states is a fundamental property which prevents them from being perfectly and deterministically discriminated. To circumvent this problem, we prese…
Gaussian Boson Sampling
Craig S. Hamilton, Regina Kruse, Linda Sansoni +3
Boson Sampling has emerged as a tool to explore the advantages of quantum over classical computers as it does not require a universal control over the quantum system, which favours…
Direct calibration of click-counting detectors
Martin Bohmann, Regina Kruse, Jan Sperling +2
We introduce and experimentally implement a method for the absolute detector calibration of photon-number-resolving time-bin multiplexing layouts based on the measured click statis…
Limits of the time-multiplexed photon-counting method
Regina Kruse, Johannes Tiedau, Tim J. Bartley +2
The progress in building large quantum states and networks requires sophisticated detection techniques to verify the desired operation. To achieve this aim, a cost- and resource-ef…
Extracting the physical sector of quantum states
Dmitri Mogilevtsev, Yong-Siah Teo, Jaroslav Rehacek +6
The physical nature of any quantum source guarantees the existence of an effective Hilbert space of finite dimension, the physical sector, in which its state is completely characte…
Driven Boson Sampling
Sonja Barkhofen, Tim J. Bartley, Linda Sansoni +4
Sampling the distribution of bosons that have undergone a random unitary evolution is strongly believed to be a computationally hard problem. Key to outperforming classical simulat…
Dual-path source engineering in integrated quantum optics
Regina Kruse, Linda Sansoni, Sebastian Brauner +4
Quantum optics in combination with integrated optical devices shows great promise for efficient manipulation of single photons. New physical concepts, however, can only be found wh…
N00N states from a single non-linear directional coupler
Regina Kruse, Linda Sansoni, Sebastian Brauner +4
In the quest for applicable quantum information technology miniaturised, compact and scalable sources are of paramount importance. Here, we present the concept for the generation o…
Driven Quantum Walks
Craig S. Hamilton, Regina Kruse, Linda Sansoni +2
In this letter we introduce the concept of a driven quantum walk. This work is motivated by recent theoretical and experimental progress that combines quantum walks and parametric…
Spatio-spectral characteristics of parametric down-conversion in waveguide arrays
Regina Kruse, Fabian Katzschmann, Andreas Christ +7
High dimensional quantum states are of fundamental interest for quantum information processing. They give access to large Hilbert spaces and, in turn, enable the encoding of quantu…
